[Base Data] Remove from shared memory and simplify (#4045)

* [Base Data] Remove from shared memory and simplify

- Removes Base Data loading from shared memory and puts it into zone.
- Changes type of `level` and `class` to `uint8_t` from `uint32_t` for consistency since we're renaming fields here anyway.
- Renames `unk1` to `hp_regen` in `base_data` table.
- Renames `unk2` to `end_regen` in `base_data` table.
- These changed fields were already mapped, we just hadn't renamed them for whatever reason.
- Regenerates Base Data repository.
- Adds `#reload base_data` to reload base data in real time.
